Thermoset or thermoplastic: what actually changes the decision

A thermoset prepreg cures by chemical crosslinking. Once the cycle is complete the resin network is set, and the part cannot be re-melted or re-formed. A thermoplastic prepreg works the opposite way: it softens on heating and solidifies on cooling with no chemical bond forming, so it can be re-processed and welded. If the part has to hold a tight tolerance under continuous heat and will never be reworked, a thermoset system is usually the conservative choice. If the process needs short cycles, recyclability or secondary welding, look at 热塑性预浸料 instead.

要拿到可用报价，请提供这些信息

Thermoset prepreg is quoted against a specification, not against a product name. Five items decide almost everything:

• 树脂体系 — epoxy, BMI, cyanate ester or vinyl ester, and the service temperature it has to survive.
• 增强体 — carbon, glass or aramid; fabric or UD; and the orientation.
• 面重与树脂含量 — stated against the target laminate, not as a preferred number.
• 工艺 — autoclave or out-of-autoclave, and the cure schedule you already run.
• Part envelope — size, ply count and any thickness tolerance that matters.

With those five we can confirm what is available for the grade and which documents come with it — grade-specific TDS, SDS and COA. Without them, any number is a guess.

储存、适用期与操作

Most thermoset systems are shipped and stored frozen. Out-time and shelf life are stated per grade and are not interchangeable between resin families. Two habits prevent most handling complaints: let the roll come up to room temperature inside its sealed bag before opening it, because condensation on a cold prepreg is the usual source of surface defects; and log cumulative out-time rather than assuming a roll is still fresh because it came out of the freezer this morning.

买家关心的缺陷模式

Most defects trace back to one of four causes: voids from an incomplete vacuum or a ramp that is too fast; resin-starved areas where resin ran before the fibre was compacted; bridging over a radius where the prepreg could not conform; and wrinkles from ply placement. Each has a distinct appearance on a cut section, which is why a photograph of the section tells us more than a description of a bad part.
