The application relates to thermoset resin composite materials comprising inter-laminar toughening particles and particularly discloses a resin system containing: (i) a thermosetting resin precursor component comprising one or more multi-functional epoxy resin precursor(s) having a functionality of at least three, preferably wherein the precursor(s) are selected from a tri-functional epoxy resin precursor and/or a tetra-functional epoxy resin precursor; (ii) a thermoplastic polyamide particle component, wherein the polyamide particles have a melting temperature TPA; and (iii) one or more curing agent(s), wherein the resin precursor component, the thermoplastic particle and the curing agent(s) are selected such that gelation of the epoxy matrix during the cure cycle of the resin system occurs at a gelation temperature TGEL which is at or below TPA. 本申请涉及包含层间韧化粒子的热固性树脂复合材料。特别地，本申请公开了种树脂系统，其含有：(i)热固性树脂前驱体组分，其包含或多种官能度为至少三的多官能性环氧树脂前驱体，优选地，其中所述前驱体选自三官能性环氧树脂前驱体和/或四官能性环氧树脂前驱体；(ii)热塑性聚酰胺粒子组分，其中所述聚酰胺粒子具有熔融温度T；以及(iii)或多
